ers; and I do hereby declare that thefollow- 1 ing is a full, clear, andexact description thereof. 7

This invention relates to pin lifters and is particularly directed to adevice for lifting coupling pins of railway cars.

In pin lifters, as heretofore constructed, it has been customary toprovide" a rock shaft coupled by means of a link or chain .with the pinand having a crank arm by. means of which it may be operated. These armsre quire a considerable effort for their proper manipulation,particularly so after they have become slightly rusty. It is usuallynecessary for the'brakeman to stand between the adjacent cars in orderto secure the proper grip upon these crank arms. This, as will beappreciated, is a precarious position, and it frequently happens-thatinadvertently the brakeman is forced against the outwardly projectingarm, or otherwise injured when the cars come together. This invention isdesigned to provide a pin lifting.

device which avoids all of the above noted defects and insures thesafety of the operator.

Objects of this invention are to provide a pin lifter which mayv beoperated by a man standing to the side of the railway car, which isoperated by a direct pull rather than by a rocking motion, and which isso arranged that the brakeman will fall away from the car if he shouldslip, and therefore be out of the danger zone.

Further objects are to provide a pin lifter which is of simple design,which is sturdy and reliable in operation, and which may be produced ata minimum cost.

An embodiment of'the invention is shown in the accompanying drawings, inwhich:

Figure l is a fragmentary end view of a railway car equipped with thepin lifter.

Figure 2 is a side elevation ofthe pin lifter, partly in section.

Referring more particularly to the drawings, 1 indicates a railway car,2 a coupling, and 3'the coupling pin. A lever A, conveniently in theform of a round bar, has an eyelet 6 at its inner end which is pivotallymounted upon a pin 5 carried between the secured'to the face of the car.This lever has a rounded intermediate portion 9 andan outwardlyprojecting arm 10, such arm being passed through the eyelet 11 of thepin 3. A transversely slida-ble rod 12 is carried by a pair of guidebrackets 13 and 14 and is provided with a downwardly projectingoperating-handle 15 adjacent the outer edge of the car and may beconveniently provided with a stop 16 adapted to abut against the guide14 when the rod occupies its dotted line position.

The inner end of the rod is provided with a bracket 17 which, by means.of a pin 18, is pivotally joined to a link 19. The upper end of the linkis provided with an eyelet 20 which engages the rounded portion 9 of thelever 4L.

outwardly projecting ears? of a bracket 8 In operating this vdevi'ce'the brakeman stands to the side of the car and is not required to standbetween adjacent cars as has heretofore been the case. to lift the pinhe pulls the handle 15 outwardly into the dotted line position, therebyforcing the link 19 against the rounded portion 9 of the lever 4 andcausing such lever to move to its dottedline position, as shown inFigure 2, thereby lifting the pin 3.

It is to be noted that the operator manipulates this device by a directoutward pull When he desires and that he is at all times out of thedanger zone. It is also to be noted that even in the event of theoperator slipping, he will fall In other words, these pin lifters may bedirectly attached to the body of thecar in i an extremely simplemannerand, due to the relatively elongated. arm 10, will cooperate withany-type of the usual coupling pins.

I claim 1. In combination, a railway car body provided with a couplinghaving a coupling pin,

a bracket mounted on said car body, a lever extending outwardly at rightangles to the plane of said car body and carried by said bracket andhaving its outer end connected 90 away from the cars and. not betweenthem.[

with said pin, a rod slidably mounted in guides secured to said carbodyand having a manipulating handle laterally spaced from saidcoupling, and an angularly arranged link connecting said lever and saidrod and lying in a plane substantially at right angles link pivotallyjoined to said rod and to an intermediate portion of said lever andlying in a plane at right angles to the plane of said lever, wherebywhen said rod is slid longitudin'ally, said lever is elevated, therebyis raising said pin. o

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of WVisconsin. f
